Hello,
I trying to install ceph but can't get it working documentation is not clear
and confusing how to do it.
I have cloned 3 machines with ubuntu 12.04 minimal system. I'm trying to
follow docs
http://ceph.com/docs/master/start/quick-start-preflight/
but got some questions:
step 4. Configure your ceph-deploy admin node with password-less SSH access
This should be done on ceph account, its't it?
next:
http://ceph.com/docs/master/start/quick-ceph-deploy/
creating directories for maintaining the configuration for ceph-deploy is
on ceph account or root?
do all following step in docs are on ceph account or root?
if on ceph account step 3. creating mon on 3 machines gives on two remote
machines these errors:
[ceph1][DEBUG ] locating the `service` executable...

[ceph1][WARNIN] neither `public_addr` nor `public_network` keys are defined

[ceph1][WARNIN] monitors may not be able to form quorum
step 4. gathering keys should it be from all mon servers?
checking status on ceph account gives:

Ceph management after installation should it be done on root or ceph
account?
I've attached typescrpi from what I have done.
I just went through your typescript and you did call `new` but not for
all the hosts you are using:
ceph-deploy new ceph0
And then you did:
ceph-deploy install ceph0 ceph1 ceph2
And finally (reason why you have issues) you tried to deploy a mon to
those hosts that were not
defined in your ceph.conf:
ceph-deploy mon create ceph0 ceph1 ceph2
You see, you need to define those as well when calling `new` like:
ceph-deploy new ceph0 ceph1 ceph2
thanks
Wojciech
